Highlighted Features

  • Weatherproof housing for use in outdoor or condensing environments
  • High accuracy
  • Replaceable Relative Humidity sensor provides fast response and superior recovery from condensing conditions
  • Small-diameter external sensor versions for measurements in tight spaces
  • Optic USB interface for fast and reliable download
  • Compatible with HOBOware and HOBOware Pro software for logger setup, graphing and analysis (HOBOware Pro is required when using the U-DTW-1 Waterproof shuttle)

HOBO data loggers require HOBOware software and a USB cable. (Note: A USB cable is included w/HOBOware Pro CD or USB software purchase). HOBOware Pro is required when using the U-DTW-1 Waterproof shuttle. See compatible items below or build your kit above.
